Improving engagement with an alcohol reduction app: the impact and importance of usability testing

Abstract

Background The usability of a technology is a key factor in its adoption. Smartphone applications present particular challenges because of their small screens and keyboards and the wide range of settings in which they are used. This presentation will describe a usability study of an application designed to help users reduce their alcohol consumption, ‘Drink Less’. Aims To gain a detailed understanding of usability of the Drink Less application in terms of the extent and manner of user engagement, the features users like and dislike, the extent to which they feel that different features of the app are easy or difficult to use, and how far the app meets their needs. Methods Two studies were conducted: a think aloud study and a semi-structured interview study. Each involved 12 participants wanting to reduce their consumption of alcohol. Transcribed responses and interviews were analysed with thematic analysis. Results Participants in both usability studies expressed desire for: onscreen guidance about to how to use the app; improved consistency in its navigation; and for the app to look and feel friendlier to use. Participants in the semi-structured interview study additionally identified different issues and suggested feature additions from their use over a period of time. Conclusions The usability study provided valuable insights about increasing user satisfaction with the app. Conducting two studies provided useful information as to the core issues present for both first time users and repeated users. The second study identified issues that may be important to secure continued engagement.
